Description

Technical Field

[0001] This invention relates to the field of non-human primate Old World monkey breeding technology, specifically to a non-human primate monkey cage door lock device and its opening and closing method. Background Technology

[0002] With the rapid development of the global biopharmaceutical industry in recent years, especially after it gained national attention and became a key industry, my country's biopharmaceutical industry chain has ushered in development opportunities. As an indispensable experimental animal for preclinical trials in new drug development and medical device research, the non-human cynomolgus monkey has become a strategic resource. Therefore, stabilizing and expanding cynomolgus monkey farming in my country is crucial for the development of biopharmaceutical technology in my country and even the world.

[0003] Because of their highly intelligent, imitative, and memory-rich brains, as well as their exceptionally dexterous hand and foot movements compared to other animals—capable of performing most actions that humans can do—crab-eating macaques face the challenge of reliably confining them to a large enclosure. During crab-eating macaque rearing, each enclosure requires multiple feedings of various feeds per day, at least one cleaning, and, along with veterinary observation and other care, the cage door needs to be opened and closed at least five times a day.

[0004] Traditional, simple mechanical locks are easy to operate, and cynomolgus monkeys can learn to unlock them after observing their keepers repeatedly, leading to escapes or other situations detrimental to breeding and experimentation. However, using commercial electronic or combination locks is not only expensive, but also inefficient, requiring keepers and veterinarians to spend a significant amount of time each day operating them. Furthermore, situations sometimes require one-handed operation; most locks that prevent cynomolgus monkeys from opening themselves still require both hands, further reducing efficiency.

[0005] Therefore, there is a need in this field for a cage door lock device and opening / closing method that is simple in structure, low in cost, easy to manufacture, suitable for human one-handed operation, and can prevent monkeys from learning to use it. Summary of the Invention

[0006] This invention provides a cage door lock device for non-human primates and its opening and closing method, the specific solution of which is as follows:

[0007] In one aspect, the present invention provides a cage door lock device for non-human primates, comprising a cage door, a T-shaped bolt lock, and a locking structure. The cage door is provided with multiple cylindrical sleeves. The T-shaped bolt lock includes a lock core and a handle. The lock core is a horizontally oriented cylindrical rod, and the handle is a vertically oriented cylindrical rod. The top end of the handle is welded to the midpoint of the lock core. Both ends of the lock core are respectively inserted into the cylindrical sleeves. The T-shaped bolt lock is movable left and right relative to the cage door. The T-shaped bolt lock has a through hole, and one end of the locking structure passes through the through hole and is detachably mounted on the T-shaped bolt lock.

[0008] In one specific embodiment, the locking structure is a triangular structure, and the locking structure includes a gripping part, an elastic part, and a locking part, which are integrally formed;

[0009] The gripping part is located on one side of the locking structure and is L-shaped;

[0010] The elastic part is located at the top of the locking structure and is an arc-shaped elastic structure.

[0011] In one specific embodiment, the locking part is composed of two ends of a locking structure. One end of the locking structure is a spiral bend section connected to the gripping part, and the other end of the locking structure is a movable section. The top end of the movable section is connected to the elastic part, and the bottom end of the movable section is engaged with the inner spiral of the spiral bend section.

[0012] In one specific embodiment, a nut is welded to one end of the movable section near the elastic part. The outer diameter of the nut is larger than the diameter of the through hole. The movable section passes through the through hole and is detachably mounted on the T-type bolt lock.

[0013] In one specific embodiment, the nut is welded using acetylene spot welding.

[0014] In one specific embodiment, the nut is a hexagonal nut or a square nut.

[0015] In one specific embodiment, the locking structure is made of stainless steel.

[0016] In one specific embodiment, the locking structure is made of a stainless steel cylinder with a diameter of 4-6 mm by bending deformation.

[0017] In another aspect, the present invention provides a method for opening and closing a cage door lock device for non-human primates, the method comprising the following steps:

[0018] Locking: First, the operator inserts the movable section into the through hole on the T-bolt lock until the bottom of the nut is in contact with the upper surface of the T-bolt lock; second, the operator grips the handle and applies force towards the handle to the movable section, causing the elastic part to deform elastically and drive the movable section to slide along the spiral bend until it slides into the spiral bend, successfully locking the locking structure.

[0019] Unlocking: First, the operator grips the handle firmly and applies force towards the moving section, causing the elastic part to deform elastically and slide along the spiral bend until it slides into the spiral bend, successfully opening the locking structure; Second, pull the locking structure out of the through hole on the T-bolt lock, and the operator grips the handle of the T-bolt lock, causing the lock cylinder of the T-bolt lock to move horizontally, completing the unlocking.

[0031] Example 1

[0032] Please refer to Figure 1-2 The illustration shows an overall structural diagram and a structural diagram of the locking structure of a non-human primate cage door lock device provided in an illustrative embodiment of this application.

[0033] like Figure 1-2 As shown, the cage door locking device for non-human primates includes a cage door 1, a T-shaped bolt lock 2, and a locking structure 3. The cage door 1 is provided with multiple cylindrical sleeves. The T-shaped bolt lock 2 includes a lock core and a handle. The lock core is a horizontal cylindrical rod in the axial direction, and the handle is a vertical cylindrical rod in the axial direction. The top of the handle is welded to the midpoint of the lock core. The two ends of the lock core are respectively inserted into the cylindrical sleeves. The T-shaped bolt lock 2 can move left and right relative to the cage door 1. The T-shaped bolt lock 2 has a through hole. One end of the locking structure 3 passes through the through hole and is detachably installed on the T-shaped bolt lock 2.

[0034] The locking structure 3 is a triangular structure. This triangular design improves the overall stability of the locking structure 3, ensures sustained elasticity, and enhances ease of operation. The locking structure 3 includes a gripping part 4, an elastic part 5, and a locking part 6, all integrally formed. The gripping part 4 is located on one side of the locking structure 3 and is L-shaped; the elastic part 5 is located at the top of the locking structure 3 and is an arc-shaped elastic structure.

[0035] The locking part 6 is composed of two ends of the locking structure 3. One end of the locking structure 3 is a spiral bending section 61, which is connected to the gripping part 4. The other end of the locking structure 3 is a movable section 62, the top end of which is connected to the elastic part 5, and the bottom end of which is engaged with the spiral inner side of the spiral bending section 61.

[0036] A nut 7 is welded to one end of the movable segment 62 near the elastic part 5. The outer diameter of the nut 7 is larger than the diameter of the through hole. The movable segment 62 passes through the through hole and is detachably installed on the T-type bolt lock 2. In this embodiment, the nut 7 is a hexagonal nut, located at 1 / 4 of the distance from the elastic part 5 on the movable segment 62. The nut 7 is welded using acetylene spot welding, which not only improves the elasticity of the stainless steel material but also fixes the position of the movable segment 62 in the through hole. That is, after the movable segment 62 is inserted into the through hole, the nut 7 blocks the upper surface of the T-type bolt lock 2, thus limiting the position of the movable segment 62.

[0037] The locking structure 3 is made of 304 stainless steel. The locking structure 3 is made by bending and deforming a stainless steel cylinder with a diameter of 4-6mm, and the two ends are bluntly ground to prevent scratching the operators or the monkeys being raised.

[0038] This embodiment illustrates a method for opening and closing the locking device of a cage door 1 for non-human primates, including the following steps:

[0039] Locking: First, the operator inserts the movable section 62 into the through hole on the T-shaped bolt lock 2 until the bottom of the nut 7 is in contact with the upper surface of the T-shaped bolt lock 2; second, the operator grips the grip part 4 with his hand and applies a force toward the grip part 4 to the movable section 62, causing the elastic part 5 to deform elastically, driving the movable section 62 to slide along the spiral bend section 61 until it slides into the spiral bend section 61, successfully locking the locking structure 3;

[0040] Unlocking: First, the operator grips the gripping part 4 and applies force towards the gripping part 4 to the movable section 62, causing the elastic part 5 to deform elastically and drive the movable section 62 to slide along the spiral bend section 61 until it slides into the spiral bend section 61, successfully opening the locking structure 3; Second, pull the locking structure 3 out of the through hole on the T-type bolt lock 2, and the operator grips the handle of the T-type bolt lock 2, causing the lock cylinder of the T-type bolt lock 2 to move horizontally, completing the unlocking.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
